SQL & PL/SQL :: Create Normal Primary Constraint During Table Creation
Mar 23, 2010
i'm new to oracle environment.how can i specify NONCLUSTERD INDEX on Primary cloumn during table creation.By default it will create clusterd index but i need non-clusterd index on it.
I'm using following stmt to create normal primary constarint during table creation,
CONSTRAINT PKFORM_PROPS PRIMARY KEY (FORM_PROPS_PK) USING INDEX TABLESPACE DB123_INDEX
how can i change the above query, so that it should create NONCLUSTERED INDEX on Primary key column.

I use Oracle 10.0.2.0.1.If I create a table with constraint key; after that I create an unique index key, I got an error. Does it mean when I create a table with constraint the unique index are automatically created and I could not create index key as I did as below?
create table test_const(ename varchar2(50) not null,
key_num number not null,
descr varchar2(100),
constraint constraint_test_const unique (ename, key_num));
create unique index test_const_idx on test_const
(
"ENAME","KEY_NUM"
)
tablespace tmp_data;
Error report: SQL Error: ORA-01408: such column list already indexed 01408. 00000 - "such column list already indexed" added [pre] tags by Sriram

I have a table say EMP with 2 fields ID and Name, with ID being the primary key. The name of the primary key constraint is ID_PK.Now my scenario is :
1. Rename the table EMP to EMP_TEMP;
2. Create an empty table EMP
3. If (data successfully loaded into EMP)
{
Drop EMP_TEMP;
}
else
{
Drop EMP;
Rename EMP_TEMP to EMP;
}
The problem here for me is the primary key constraint. When I am in 2, I cannot create the primary key constraint again since the old one is still in tact. If I go ahead to drop the original pk constraint and re-create a new one in 2, then in case of else part , I need to get the constraint again while renaming the original table.

I have to create primary key using local on a partitioned table.
Since the table is huge it has to be done parallel. Following stmt is giving error
alter table XYZ add CONSTRAINT PKN_XYZ PRIMARY KEY (ID,LogDtTm)
USING INDEX LOCAL parallel 25 INITRANS 5 TABLESPACE OLTP_IDX_TS ;

I have in a plsql block somewhere a statement like
INSERT INTO TABLE1( id , col)
SELECT id, col
FROM TABLE2;
This statement returns an error ORA-00001: unique constraint because id is a primary key on TABLE1. I would like to know what is the value of id that raised the exception.

when I check one database, I noticed that the primary key constraint is in UNUSABLE status. But when I check the table, the table DDL itself,the below query mentioned.
ALTER INDEX "COMMON_DATA"."PK_DISE_MOBILE" UNUSABLE ENABLE
suggest whether I need rebuild this index? if I rebuild this index, will it useful for me for the performance improvement? But the table has only 578234 records.
Table DDL
CREATE TABLE "COMMON_DATA"."DISE_MOBILE_INSTALLATION"
( "M_DBASE_ID" VARCHAR2(2),
"COMPANY_NUMBER" NUMBER(3,0),
"M_ACCT_ID" NUMBER(8,0),
"ACCOUNT_CREATION_DATE" DATE,
"ORDER_NUMBER" VARCHAR2(15),
"ORDER_CREATION_DATE" DATE,
"ORDER_CREATION_METHOD" VARCHAR2(1),
"CONTRACT_TERM" VARCHAR2(3),
"GROUP_ID" VARCHAR2(6),

I am trying to add a primary key constraint to a cluster table on the cluster key columns whitout creating additional indexes.
Example:
CREATE CLUSTER CL1
(A NUMBER)
SIZE 100;
CREATE UNIQUE INDEX CICL1 ON CLUSTER CL1;
gives
ORA-01715: UNIQUE may not be used with a cluster index
CREATE INDEX CICL1 ON CLUSTER CL1;
CREATE TABLE CLT1 (A NUMBER,B NUMBER,primary key (A) using index cicl1) CLUSTER CL1 (A)
gives
ORA-14196: Specified index cannot be used to enforce the constraint.
CREATE TABLE CLT1 (A NUMBER,B NUMBER, primary key (A)) CLUSTER CL1 (A)
creates an additional system generated index SYS_C....
Is there any way to utilize the cluster key to ensure the uniqueness/primary key constraint of the cluster key columns of table CLT1 ?

Oracle 10g, Windows XP
There is an interface table and there is an normal transcational table..interface table is being compared with normal table and if match found the result is dumped into another normal table.
I am using two cursors one is to query the interface table and in a for loop pass the results to the second cursor..The interface table is having 5000 + rows and the transcation table is having more than 3.7 millions ..and the program is taking lots of time to execute..took almost 35-45 minutes..
create table x_interface /* INterface table */ -- 5000 + rows
( name varchar2(80), addr_line1 varchar2(35), addr_line2 varchar2(35), addr_line3 varchar2(35),
addr_line4 varchar2(35), addr_line5 varchar2(35), addr_line6 varchar2(35), suffix varchar2(35),

I have table EMP & DEPT.
Can you give me sample "check" constraint so that when I enter an EMP (with status='active') without matching DEPT entry, the process will fail?
It will allow to enter EMP with status='inactive' only even if no matching DEPT entry. So foreign_key will not apply.

, I'd like to create a constraint (when creating a table) that checks to ensure that the 'Year' entered is less than or equal to the current year (based off SYSDATE). Per the code below, I keep getting the same error, "missing right parenthesis". I've spent more than an hour trying different ways to get this to work, but I've been failing miserably. I am using Oracle 11g Express.
CREATE TABLE TEST (Name VARCHAR2(7) PRIMARY KEY, Year NUMBER(4), CONSTRAINT TEST_YEAR_CK CHECK (Year <= (TO_NUMBER(TO_CHAR(SYSDATE, 'YYYY')))FROM DUAL);
*ERROR at line 4:ORA-00907: missing right parenthesis

A Master form in a tabular format. Id is a display item. I want to auto generate Id with following query.
select nvl(max(issue_id),0)+1 into :issue_mt.issue_id from issue_mt;
It works:
1)When each record is saved before creating new record.
It doesn't work:
2)If multiple records are entered with out saving each record.
What to do to generate unique Id in both cases?

Create table X(
var1 varchar2(20) null,
var2 varchar2(20) not null,
constraint pk_var1 primary key(var1)
We all know Primary key doesnt treat NULL as a value. But the above statement is fine to be executed without problem.
Is this something to be highlighted? or am i not right in understanding 'var1 varchar2(20) null '?

I'm trying to create a sequence for a primary key to simply auto-increment by the default of 1. I have a sql script written to generate mt tables, and I'm not sure how to modify the script to include the sequence. I also just want the sequence for a specific column, ie, PK, not the PK in all tables.
Here's a snippet from my script:
create table image
(
image_id int NOT NULL,
source_id int NOT NULL,
CONSTRAINT image_id_pk PRIMARY KEY (image_id),
CONSTRAINT fk_source_id FOREIGN KEY (source_id) REFERENCES source(source_id)
);
Would I add the create sequence statement right after the create table, and if so, how do I apply the sequence to only 1 table and a single column?

What is difference when you issue a create controlfile with "standby" keyword on the primary database
ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/path/db_stby.ctl';
vs. creating a control using
ALTER DATABASE BACKUP CONTROLFILE to '/path/db_control.ctl';
what does ORACLE put into the standby control that is "extra"? ie. what is the difference between a standby control file and a normal control file?

how to i insert a constraint of words into the table example below.I am new to this stuff man.
Create table Orders
(
orderID Number(8) Primary Key,
orderDate Date Not Null,
methPmt Varchar2(10),
custID Number(5),
orderSource Number(2),
Foreign Key(custID) Reference Customer(custID),
Foreign Key(ordersource) Reference OrderSource(ordersource)
);
The catch is I am required to enter a constraint of the methPmt will only take values of "CASH", "CREDIT" or "CHEQUE" only.
How am I suppose to enter this constraint value into the creation of this table?
